value: Add a FIXME 2.0 for a fraction ranges optimization

Currently we leak the internal representation of them as two GValues that
contain a fraction. Without this we could store fraction ranges as
  data[0] = (min_n << 32) | (min_d)
  data[1] = (max_n << 32) | (max_d)
and wouldn't require an additional allocation per range.
